Native Devtools MCP, a free mcp server tool by Sh3ll3x3c, is developed primarily in Rust. It enables AI agents and MCP clients to interact with various computing environments. This powerful utility extends the capabilities of large language models by allowing them to observe user workflows and simulate input. It connects to native desktop applications, browsers, and Android devices, providing a unified interface for automation. Its design emphasizes local execution, ensuring data like screenshots and input remain on the user's machine without external API dependencies.

What does Native Devtools MCP connect to?

Native Devtools MCP serves as an MCP server for computer use and browser automation. It connects to native desktop applications on macOS and Windows, enabling interaction with various programs. Additionally, it integrates with Chrome and Electron browsers via the Chrome DevTools Protocol (CDP) for advanced web automation. The tool also supports Android devices through ADB, allowing for mobile automation tasks. This broad connectivity makes it a versatile solution for automating diverse digital environments.

Core features and tools

Native Devtools MCP exposes a rich set of callable tools for automation. These include screenshot, OCR, click, type, find_text, and template matching for general application interaction. For browser automation, it offers Chrome/Electron CDP. Android device management is handled by android_list_devices and android_connect. Other specific tools are take_screenshot, find_text, click, type_text, find_image, load_image, take_ax_snapshot, ax_click, ax_set_value, ax_select, and start_hover_tracking.

Who is it for?

Native Devtools MCP is designed for AI agents and MCP clients, especially large language models that need to interact with and observe user workflows. It supports confirmed compatible AI clients such as Claude Desktop, Claude Code, and Cursor. The tool targets scenarios where automation requires controlling various applications, browsers, or mobile devices. It is particularly useful for AI systems needing to simulate human input or extract information from visual interfaces. Skip this if your automation tasks do not involve local desktop, browser, or Android device interaction.

How to get started

No credentials are required, as Native Devtools MCP runs 100% locally with no API dependency. The official documentation does not explicitly state the supported transport protocols for Native Devtools MCP.

Use cases

• Computer Vision and Input Simulation: Automates any application interaction using screenshots, OCR, text or image finding, and simulating clicks and typing.
• Browser Automation: Controls Chrome and Electron applications via Chrome DevTools Protocol for DOM interactions, form filling, navigation, and JavaScript evaluation.
• Android Device Automation: Manages Android devices, takes screenshots, performs uiautomator text lookups, simulates input, and manages applications over USB or Wi-Fi.

Native Devtools MCP offers a powerful, locally executed solution for AI agents requiring broad interaction capabilities. Its Rust foundation supports automation across desktop applications, web browsers, and Android devices without external API dependencies, ensuring data privacy. The tool provides a diverse set of callable functions for computer vision, input simulation, and advanced protocol-based control. It is an essential component for LLMs needing to observe and manipulate complex user interfaces. Try automating a desktop application by taking a screenshot and using OCR to find text.
